Module 1 : Electric Field Intensity (Electric Stress)
Lecture 1:  An introductory lecture
Levels of high voltage:
World over the levels are classified as:
  • LOW
  • MEDIUM
  • HIGH
  • EXTRA and
  • ULTRA HIGH Voltages
  • However , the exact magnitude of these levels vary from country to country. Hence this system of technical terms for the voltage levels is inappropriate .
  • In most part of the world even 440 V is considered to be high voltage since it is dangerous for the living being.
  • Hence it would be more appropriate to always mention the level of voltage being referred without any set nomenclature .
